That's why I put the (larger) there - if you are a small company maybe you can not keep up a separate office infrastructure from your deployment / test systems in case of SW development. If you are a large enterprise and use Microsoft infrastructure, then either the people making the decisions in IT are getting a lot of bribes, or they are really really stupid :) Or both.

And I mean that absolutely without anger against Microsoft, and purely in terms of security nightmare and waste of office productivity because using a contemporary windows system wastes so much more time of any given user that each desk worker probably loses 20-70% productivity compared to a lean operating system (and that would include something like Windows 2000 / XP).
